FOREWORD 

This Indian Standard was adopted by the Bureau of Indian Standards, after the draft finalized by the Industrial 
Safety and Chemical Hazards Sectional Committee had been approved by the Chemical Division Council. 

Hydrofluorocarbons (HFCs) are categories of synthetic chemicals that are being used as alternatives to the ozone 
depleting substances (ODS), which are being phased out under the Montreal Protocol and Clean Air Act 
amendment of 1990. Because HFCs do not directly deplete the stratospheric ozone layer, they are not controlled 
by Montreal Protocol. 

These compounds, however, along with sulfiir hexafluoride are potent greenhouse gases. In addition to having 
high global warming potentials, many HFC's have extremely long atmospheric life times, resulting in their essentially 
irreversible accumulation in atmosphere. 

HFC- 134a is an ozone friendly CFC substitute. The t)zone layer in the stratosphere which protects the earth from 
ultraviolet radiation from the Sun is getting depleted by various chemicals/substances released in the atmosphere 
including chlorofluoro carbons (CFC) used in several industries such as refrigeration, air conditioning, electronics, 
foams etc. Montreal Protocol to which India became a signatory in 1992, prohibits the use of CFCs beyond the 
year 2010, HFC- 134a is one of the recommended CFC substitute in refrigeration, air conditioning and aerosol 
Industries and is a much preferred one for several technical, economic and safety reasons. 

There is no standard on this subject published by ISO. This standard has been prepared indigenously based on the 
available data and information. In preparation of this code considerable assistance has been derived from the

4.3 Chemical Properties 

4.3.1 HFC-134a vapours will decompose when 
exposed to high temperature from flames or 
electric resistance heaters. Decomposition may 
produce toxic and irritating compounds, such as 
hydrogen fluoride. The pungent orders will irritate the 
nose and throat and generally force people to evacuate 
the area. Therefore, it is important to prevent 
decomposition by avoiding exposure to high 
temperatures. 

4.3.2 HFC- 134a / Poly alkylene glycol (PAG) and 
HFC- 134a / Polyol ester (POE) solutions have 
acceptable chemical stability. HFC- 134a molecule is 
as chemically stable as CFC-12. HFC-134a and 
CFC-12 are chemically compatible with each other, 
this means they do not react with each other to 
form other compounds. However, when the two 
materials are mixed together, they form azeotrope, 
which is difficult to separate. These mixtures can not 
be separated in an on-site re-cycle machine or in the 
typical facilities of an offsite reclaimer. Mixtures of 
HFC- 1 34a and CFC- 1 2 will usually have to be disposed 
of by incineration. 

4.3.3 HFC- 134a is compatible with steel, copper, 
aluminium and brass. 

4.3.4 Incompatibility 

Finely divided metals, magnesium and alloys 
containing 2 percent magnesium. It can react violently 
in contact with alkali or alkali earth metals such as 
Na, K, or Ba. 

4.4 Fire and Explosion Properties 

4.4.1 Auto Ignition Temperature^ 770°C 

4.4.2 Flammability 

HFC- 134a is non-flammable at ambient temperature 
and atmospheric pressure. However, it may be 
combustible at pressures as low as 5.5 psig at MTC, 
When mixed with air at concentrations generally 
greater than 60- vol. percent air. 

4.5 Corrosion Properties 

Not-corrosive. 



5 TOXICINFORMATION AND HEALTH 

EFFECTS 

5.1 Toxicity 

HFC- 1 3 4a has very low acute and subchronic inhalation 
toxicity and is not genotoxic. 

5.2 Routes of Entry 
Inhalation, skins and eye contact. 

5.3 Health Effects 

5.3.1 Inhalation 

HFC- 134a poses no acute or chronic hazard when 
exposures are maintained below recommended 
acceptable exposure limits (AEL) of 1 000 ppm on 
8 or 12 hour time-weighted average (TWA) established 
by AIHA. 

NOTE — AEL is an airborne inhalation exposure limit that 
specifies time-weighted average concentrations to which nearly 
all workers may be repeatedly exposed without adverse effects. 

5.3.2 Asphyxiation 

Inhaling high concentrations of HFC- 1 34a vapour may 
cause temporary nervous system depression with 
anesthetic effects such as dizziness, headache, 
confusion and loss of consciousness. It can act as 
asphyxiant by limiting available oxygen. Higher 
exposures to vapours may cause temporary alteration 
of the heart's electrical activity with irregular pulse, 
palpitation or inadequate circulation. Inhaling higher 
concentrations of HFC- 134a vapour may cause cardiac 
irregularities and possibly cardiac arrest. 

5.3.3 Skin and Eye Contact 

At room temperature, HFC- 134a vapours have little 
or no effect on the skin. However, in liquid form, HFC- 
134a can freeze skin or eyes on contact causing 
frostbite. 

6 PERSONAL PROTECTIVE EQUIPMENT 

6.1 General 

Personal protective equipment is not an adequate 
substitute for good, safe working conditions. Adequate 
ventilation and intelligent conduct on the part of 
employees is essential. One should keep firmly in mind 
that personal protective equipment protects only the 
person wearing it, and other unprotected workers in 
the area may be exposed to danger. 

6.2 Non-respiratory Equipment 

Personal protecting equipment should include non- 
respiratory equipment like splash proof safety goggles 
and face shield when working with liquid for eye 
protection. Where exposure to cold equipment vapours 
or liquid may occur, employees should wear special 
clothing designed to prevent the freezing of body 



IS 15548 : 2005 



tissues. All protective clothing ( suits, shirts witJ|if^ 
sleeves, insulated gloves) should be clean;-: availabjj;^- 
each day, and put on before work. Trousers should be 
worn outside boots or overhigh top shoes to shed 
spilled liquid. 

6.3 Respiratory Equipment 

If a large release of HFC- 134a vapour occurs, such as 
from a large spill or leak, the vapours may concentrate 
near the floor or low spots and displace the oxygen 
available for breathing, causing suffocation. An 
approved self contained breathing apparatus with a full 
face piece operated in positive pressure mode should 
be used when entering tanks and other areas where 
vapours might exist. 

7 STORAGE, HANDLING, LABELLING AND 
TRANSPORTATION 

7.1 Storage 

7.1.1 General Precautions 

7.1.1.1 HFC- 1 3 4a must be stored to avoid contact with 
heat, flames, sparks and air. 

7.1.1.2 Vessels, containers, transfer lines, pumps and 
other equipment should not be exposed to high 
temperature sources (such as welding, brazing and open 
flame) until they have been thoroughly cleaned and 
found free of vapours. Any maintenance job on such 
equipment should be done under the variety of safety 
work. 

7. 1 . 1 .3 Only non-sparking tools and equipment should 
be used while opening and closing containers of 
HFC- 134a. 

7.1.1.4 The building shall have good low and high 
level natural ventilation. In areas where natural 
ventilation is not possible, forced ventilation 
equipment should be installed. 

7.1.2 Bulk Storage 

7.1.2.1 The storage tanks shall be designed as per 
standard code. 

7.1.2.2 Storage tanks should be equipped with pressure 
gauge, liquid level gauge, safety release valves and 
excess flow valves. 

7.1.2.3 Storage tanks should normally be evacuated at 
the start of filling, and should never be filled while under 
positive air pressure. 

7.1.2.4 Tank pressure should never be allowed to 
exceed 300 psig when filling with HFC- 134a. Relief 
devices on the tanks usually prevents this. 

7.1.2.5 Tank pressures should be monitored routinely. 

7.1.2.6 Air lines should never be connected to storage 
tanks. 



Id 3 Storage of Cylinders 

7.1.3Ti The Cylinders of HFC-134a should be kept 
out of direct sunlight, particularly in warm weather. 
HFC- 134a expands significantly when heated, thereby 
reducing the amount of vapour space left in the cylinder. 
Once the cylinder becomes liquid full, any further rise 
in temperature can cause the cylinder to burst, resulting 
in serious personal injury. 

7.1.3.2 Never allow the cylinders to get warmer than 
52 T, 

7.1.3.3 Cylinders should always be raised above dirt 
or damp floors to prevent rusting. 

7.1.3.4 The storage area should be away from corrosive 
chemicals or fiimes to avoid damaging effects on the 
cylinder and threaded area of the valve. The cylinders 
of HFC- 134a should be kept in cool, dry and properly 
ventilated areas. 

7.2 Handling 

7.2.1 General 

7.2.1.1 HFC-134a should be handled wearing an 
approved self contained breathing apparatus, chemical 
resistance gloves and safety goggles and other 
protective clothing {see 6). 

7.2.2 Handling of Cylinders 

1.22 A Before filling the cylinder with HFC- 134a, 
check and confirm its validity. It shall have valid test 
certificate from the concerned authorities. 

7.2.2.2 Cylinders should never be subjected to rough 
handling or to abnormal mechanical shock such as 
dropping, bumping, dragging or sliding. They should 
be kept in vertical position. 

7.2.2.3 Lifting magnet or sling ( rope or chain ) which 
may produce sparks should not be used. 

7.2.2.4 While handling by crane or derrick, a safe 
platform or cradle should be used. 

7.2.2.5 Cylinders of HFC- 134a whether empty or filled 
should not be used as rollers, supports or for any 
purpose other than to carry HFC- 134a. 

7.2.2.6 Protect cylinders from any object that will 
result in abrasion in the surface of the metal. 

7.2.2.7 Never tamper with the safety devices in the 
valves. 

7.2.2.8 Use only standard colour code for HFC- 134a 
cylinders, 

7.2.2.9 Before evacuating cylinders, any remaining 
refrigerant should be removed by a recovery system. 

7.2.2.10 Vacuum pump discharge lines should be free 



IS 15548 : 2005 



of restrictions that could increase discharge pressures 
above 15 psig and result in the formation of 
combustible mixtures. 

7.2.2. 1 1 Cylinders should normally be evacuated at the 
start of filling, and should never be filled while under 
positive pressure. 

7.2.2.12 Filled cylinders should periodically be 
analyzed for air. 

7.2.2.13 Empty cylinders should be stored separately 
from filled cylinders and fasten empty tag on cylinders 
immediately upon emptying. 

7.3 Labelling 

7.3.1 Each vessel containing HFC-134a should carry 
an identification label or stencil. 

7.3.2 Label should be as per rules and regulations. 

7.4 Transportation

7.4.3.2 The trucks should not be parked under direct 
sunshine for long duration. 

7.4.3.3 No repairs involving gas cutting, welding etc, 
should be done during transportation period. If required 
at all, repairs should be done by authorized and 



competent personnel of Maintenance Department/ 
Plant who are deputed by manufacturer/supplier. 

7.4.3.4 The driver should physically inspect complete 
mounting periodically and immediately report any 
abnormality to the supplier. 

7.4.3.5 In case of emergency (for example leaks, 
fires etc), the following measures should be taken 
immediately; 

a) Stop the engine, 

b) Notify police and fire brigade immediately, 

c) Mark roads, warn other road users, 

d) Keep public away, and 

e) In case of leak, avoid open flame near spillage. 

7.4,4 Drivers Training 

7.4.4.1 The basics of any effective safety programme 
for transportation of HFC- 134a is adequate training. 

7.4.4.2 Each driver must be carefully selected and 
receive adequate amount of classroom training, audio- 
visual instructions and job training. 

7.4.4.3 The driver must carry material safety data sheet

8 SPILLAGE, LEAKAGE AND WASTE 
DISPOSAL 

8.1 Spillage/Leakage 

8.1.1 Frequent inspection of equipment, containers and 
vessels containing HFC- 134a should be made to detect 
or prevent leaks. 

8.1.2 If spills or leaks of HFC- 1 34a occur, only properly 
protected personnel should remain in the area and entry 
to others should be prohibited. 

8.1.3 Every organisation handling HFC-i34a must 
form Emergency Response Team which is available 
round the clock. Spills or leaks should be handled by 
Emergency Response Team specifically trained to 
handle emergency situations. 

8.1.4 In case of major spill or leak, the area should be 
evacuated immediately. Vapours may concentrate near 
the floor, displacing available oxygen. 

8.1.5 The area of leak must be ventilated using blowers 
or fans to circulate the air at floor level. 



IS 15548 : 2005 



8.1.6 Use self contained breathing apparatus while 
going to close valves or repair source of leak. 

8.1.7 Avoid open flames near spillage. 

8.1.8 If source of leak is a cylinder and the leak can 
not be stopped in place, remove the leaking cylinder to 
a safe place in the open air and repair leak. 

8.1.9 Prevent liquid from entering sewers, sumps or 
pit areas, since vapour can create suffocating 
atmosphere. Capture material for recycle or destruction 
if equipment is available. 

8.2 Leak Detection 

8.2.1 Leak detection is important for refrigerant 
conservation, equipment protection and performance, 
reduction of emissions and protection of those coming 
in contact with the system. 

8.2.2 No leak testing should be performed with HFC- 
134a and air in the system. HFC- 134a may be safely 
pressured with dry nitrogen. 

8.2.3 Leak detectors may be used for pin pointing 
specific leaks or for monitoring an entire room on a 
continuous basis. 

8.2.4 There are two types of leak detectors, leak 
pinpointers and area monitors. Before purchasing either 
type, several equipment factors should be considered, 
including detection limits, sensitivity and selectivity. 
Fluorescent dyes compatible with lubricant and HFC- 
134a can also be added to a system for leak detection. 

8.3 Waste Disposal 

Disposal refers to the destruction of used HFC- 134a. 
Disposal may only be necessary when HFC- 134a has 
become badly contaminated with other products and 
no longer meets the acceptance specifications of 
reclaimers. Be sure to check the qualifications of any 
firm before sending them used HFC- 134a. 

9 RECOVERY, RECLAMATION AND 
RECYCLING 

9.1 Recovery 

9.1.1 Recovery and re-use of HFC-134a is important 
from an environmental stand point. 

9.1.2 HFC- 134a may be recovered from refrigeration 
equipment using on-site equipment or portable recovery 
devices containing compressor and an air cooled 
condenser. 

9.1.3 Known venting of HFC-134a during the 
maintenance, servicing or disposal of refrigeration 
equipment should not be done. 

9.2 Reclamation 

Reprocessing of used HFC-134a should be done as 
far as possible. 



9.3 Recycling 

Refrigerant recycle refers to the reduction of used 
refrigerant contamination using devices that reduce oil, 
water, acidity and particulates. 

10 FIRE PREVENTION AND FIRE FIGHTING 

10.1 Fire Prevention 

10.1.1 HFC-134a is not flammable at ambient 
temperature and atmospheric pressure. Avoid open 
flames near source of leak. 

10.1.2 Cylinders may rupture under fire conditions 
and decomposition of HFC- 134a may occur. This will 
produce toxic and irritating compounds. 

10.2 Fire Fighting 

10.2.1 In case of fire in the area where cylinders are 
stored, cool cylinders with water spray. Self contained 
breathing apparatus with full face-piece and protective 
clothing may be required if cylinders rupture or release 
under fire conditions. 

10.2.2 Use appropriate fire extinguishing media as 
appropriate for combustibles in the area. 

11 TRAINING AND HEALTH MONITORING 

11.1 Employee Education and Training 
11.1,1 Training

IS 15548 : 2005 



12 FIRST AID 

12.1 Inhalation 

12.1.1 Inhalation of HFC- 134a vapours causes 
irritation and at high concentrations may result in 
asphyxiation, cardiac irregularities and possibly 
cardiac arrest. 

12.1.2 Intentional misuse or deliberate inhalation of 
HFC- 134a may cause death without warning. This 
practice is extremely dangerous. 

12.1.3 If high concentrations are inhaled, immediately 
remove the person to fresh air. Keep person calm. If 
not breathing give artificial respiration. If breathing is 
difficult give oxygen. Call a physician. 

12.2 Skin Contact with Liquid HFC-134a 

Immediately flush skin with plenty of water for-at 
least 15 min. Remove contaminated clothing. 



Clothing may adhere to the skin in case of freeze 
burns. In case of frostbite, flush the exposed area 
with luke warm water or gently warming affected area. 
Wash contaminated clothing before reuse. If 
symptoms (irritation or blistering) develop get 
medical attention. 

12.2.1 Eye Contact 

In case of contact, immediately flush eyes with plenty 
of water for at least 1 5 min, lifting eyelids occasionally 
to facilitate irrigation. Seek medical attention 
immediately. 

12.2.2 Antidote/Dosage 

Because of possible disturbance of cardiac rhythum,
